“Wait and see,” replied Mrs. Merrill and she led the way back to their hotel. Mary Jane supposed they must be going back for bathing suits but not so. They didn’t go to their room; they went down a long hallway and up some stairs and along another hall. And by that time, Mary Jane heard noises that sounded exactly like the sounds folks make when they are in swimming and having a jolly time.

“Why, Mother!” she said in amazement, “do they keep the swim in the house down here?”

“Sounds like it, doesn’t it?” answered Mrs. Merrill and she stopped at a window long enough to buy three tickets, one pink and two blue. “Sounds exactly like it—let’s look.” And she led them through a doorway.

Such a sight as the girls saw then, they never had imagined! In a great room, surrounded with balconies on which folks walked and danced and played, was a large tank of beautifully clear water. And in this tank some fifty or more folks were swimming and playing. At one end the children played and swam and at the other end the big folks who evidently could swim better or walk in deeper water were enjoying themselves.

Mary Jane took a long breath as she looked in amazement about her, then she said, “Come on, Mother! Let’s do it too!”

“Oh, may we?” exclaimed Alice rapturously; “will they let us?”

“That’s what our tickets are for,” explained Mrs. Merrill. “And we dress right down in these nice dressing rooms at this end.”

Five minutes later the two girls, with their mother close behind, were gingerly stepping into the water as it lapped on the marble steps at the end of the pool. Mary Jane anxiously watched the first touch of the water, then a happy expression came over her face and she exclaimed, “It isn’t cold and it isn’t hot, Mother. It’s just like I am.”

Of course Mary Jane didn’t know how to swim but both Alice and Mrs. Merrill could swim a little and they took turns holding Mary Jane’s chin and showing her how it was done. Mary Jane had no trouble getting her feet up—she got them up so far out of the water that her swimming was more splashing than swimming but it was fun for them all just the same. Nobody thought a bit about time till suddenly Alice looked at the great clock that was at one end of the pool.

“Mother!” she cried, “it’s quarter to eleven!”
